YORKVILLE UCS1B Unity Series Passive Subwoofer (Ultrathane Black)

YORKVILLE UCS1B Unity Series Passive Subwoofer (Ultrathane Black)
  • The UCS1 is the ideal passive subwoofer to use with the Unity™ U15 or U215 loudspeaker systems. This 1000-watt 8-ohm cabinet takes full advantage of its horn-loaded design to deliver fierce bottom end from a surprisingly compact, single 15-inch loaded passive subwoofer.

    The performance UCS1 delivers from a box this manageable in size is the direct result of outstanding loudspeaker cabinet design. Optimized horn flare geometry careful attention to the front and rear internal chamber dimensions, as well as the use of a high performance long excursion 15-inch driver gives the UCS1 surprising high output volume and extended bass response for a subwoofer cabinet occupying only a total volume of just over 11 cubic feet.

    The UCS1 is made with a solid 15mm 11-ply birch plywood cabinet construction and has a heavy gauge perforated metal grill to protect the components. Integrated wheels and bar handles make moving and stacking the UCS1 as easy as it can possibly be for a subwoofer in this class.

    The UCS1 comes in a black carpet covering to mate with the U15 and U215 , or is available in a black painted Ultrathane finish ( UCS1B ) for use with the Ultrathane painted versions of the Unity™ loudspeakers. ( U15B and U215B ).
